• How safe are U.S. subways?

    In a report last year, the GAO said: “Certain characteristics of mass transit systems, such as multiple access points and limited barriers to access, make them inherently vulnerable to terrorist attack and therefore difficult to secure; high ridership, expensive infrastructure, economic importance, and location in large metropolitan areas or tourist destinations also make them attractive targets for terrorists because of the potential for mass casualties and economic damage”

  • The Los Angeles-Long Beach port complex uses a variety of means to detect WMD

    The Los Angeles-Long Beach port complex uses the latest — together with the simplest — technology in trying to prevent weapons of mass destruction from being smuggled through the port; among these means used: a $3 million high-tech screening ship, a radiation-detecting helicopter and a badge-carrying black Labrador retriever that can sniff out chemical and biological weapons

  • U.S.-bound ship cargo to get more scrutiny

    The goal of screening 100 percent of U.S.-bound cargo containers is may not be reached any time soon, but new cargo-reporting requirement stipulates that ocean carriers and importers submit additional details about U.S.-bound cargo twenty-four hours before it is loaded onto vessels in foreign seaports

  • New high-precision chemical detector to be commercialized

    A start-up launched by the University of Delaware is preparing to commercialize a high-precision detector — a planar-array infrared spectrograph — that can identify biological and chemical agents in solids, liquids, and gases present at low levels in less than a second

  • New tool detects -- and neutralizes -- pathogens in mail

    Using the mail as a tool for bioterror attacks may or may not kill many people, but it will paralyze a company or an organization; the psychological damage is incalculable; new tool offers mail-room protection

  • DARPA seeking to improve bio-threat detectors

    The agency is requesting proposals for a device that would enable faster, more accurate detection of a broad range of biological agents; DARPA hopes to create a biosensor that would identify viral and bacterial threats, and do so using a natural first-line of defense: human antibodies

  • Reveal Imaging awarded $3.9 million for personnel inspection system

    The company said it plans to use multiple sensor technologies and automation to avoid the need for human operators to separate threats from harmless objects using multiple monitors

  • Backscatter technology: the future of airport security scanning?

    Manchester Airport is testing backscatter scanning technology from Rapiscan; the Rapiscan system works by bouncing X-rays off an individual’s skin to produce an outline image of the person’s body

  • Imagining new threats -- and countering them

    DHS air transport security lab is in the business of imagining new threats — then developing the technologies to counter them; their dream? To build a “tunnel of truth” in each airport lined with hidden sensors, scanners, and rays; passengers would get zapped and sniffed as they passed, and would not need to take off their shoes, toss their liquids, or anything else

  • Kachemak sees growing interest from military, law enforcement

    Alaska-based Kachemak Research Development developed an advanced vehicles’ undercarriage inspection system; the military and law enforcement are interested

  • O'Hare gets grant for baggage screening system

    DHS’s push for better baggage screening at U.S. airports continues; the latest recipient of baggage screening upgrade grants: Chicago’s O’Hare

  • Princeton, Rice researchers develop new sensor for nitric oxide

    Researchers develop new nitric oxide detector; the sensor could now be incorporated into a portable, shoe-box-sized system ideally suited for mass deployment in large-scale unattended sensor networks

  • Smiths Detection, AeroVironment show chemical-sensing UAV

    UAV technology combined with chemical sensors and advanced algorithms allow rapid aerial chemical detection and tracking

  • New advanced sensors developed

    Queen’s University Belfast researchers use Raman spectroscopy, which involves shining a laser beam onto the suspected sample and measuring the energy of light that scatters from it to determine what chemical compound is present; they mixed nanoscale silver particles to amplify the signals of compounds

  • New York City to expand Ring of Steel's coverage

    The system of surveillance cameras; license-plate readers; and chemical, biological, and radiological sensors that protect lower Manhattan will expand to cover mid-town
